ANSWER: 0.5 amps
STEP BY STEP:
your given that...
voltage (amps) = 6
resistance (ohms) = 12
and that your equation to find current is....
current = voltage / resistance
so you would....
first. plug in 6 for the numerator (voltage)
second. plug in 12 for the denominator (resistance)
third. divide 6 by 12
giving you your answer of 0.5 amps
